The tool preferably includes a handle member held in sliding engagement with a base member, for example, by a snap-fit, wherein the support portion is part of the handle member, and a distal segment of the base member is terminated by the dislodging element. A tool kit may include a plurality of base members, each one including a different type of dislodging element, from which an operator may select for snap-fitting to a handle member of the kit.Type: GrantFiled: August 31, 2017Date of Patent: October 29, 2019Assignee: Medtonic, Inc.Inventor: Daniel C. Oster

Patent number: 10456559Abstract: A cannulated tube protector comprising a main body, a first pair of securing members extending from the main body, a second pair of securing members extending from the main body, and a splinting member comprising a viewing door. The viewing door is structured to open thereby exposing a viewing aperture, defined as a doorway. The doorway extends from a first surface of the main body to an opposing second surface of the main body.Type: GrantFiled: November 8, 2018Date of Patent: October 29, 2019Inventor: Marie-Andrea I Wilborn

Patent number: 10456561Abstract: A non-compliant high strength balloon (10) includes a reinforcement member (30) formed of a sleeve of woven or braided strengthening elements (32, 34). There are provided circumferential strengthening elements (32) which are pre-tensed in order to remove any undulations within the strengthening elements (32) and to ensure that these have a precise annular size. On the other hand, the longitudinal strengthening elements (34) have undulations therein. The pre-tensing of the strengthening elements (32) ensures that the balloon will not stretch during pressurization thereof, which can occur when the circumferential strengthening elements have undulations therein, which will be natural artefacts of a weaving or braiding process. The undulations in the longitudinal strengthening elements (34) provides the balloon with increased longitudinal flexibility.Type: GrantFiled: April 8, 2015Date of Patent: October 29, 2019Assignee: Cook Medical Technologies LLCInventors: Steen Aggerholm, Thomas Lysgaard

Patent number: 10456562Abstract: Devices, methods, and systems are provided for sealing a lung region. The target lung compartment is accessed and isolated via an isolation catheter. Fluid is delivered into the target lung compartment such that the target compartment is pressurized and the fluid flows through the collateral flow channel. A sealing agent is injected into the isolated lung compartment such that the agent is carried by the fluid to the collateral flow channel, thereby sealing the collateral flow channel. Variables of air flow may be measured or analyzed prior to injection of the sealing agent, or the sealing agent may be introduced into the region after a suitable time has elapsed.Type: GrantFiled: January 20, 2016Date of Patent: October 29, 2019Assignee: Pulmonx CorporationInventors: Sri Radhakrishnan, Ryan Olivera

Patent number: 10456565Abstract: A drainage catheter system includes an elongate tube with proximal and distal ends and a filament extending the tube that is adjustable to create a closed loop at the distal end of the tube when the filament is retracted relative to the tube. The filament is coupled to the tube such that the filament and tube are prevented from being separated in the event that the tube and filament are cut at the proximal end at the conclusion of a drainage procedure. The filament can be attached to the tube near the distal end. The filament can be attached to the tube along its length. The catheter system can also include a retraction mechanism having a first fixed position and second fixed position, where the second fixed position retracts the filament proximally relative to the first fixed position by actuating a plunger.Type: GrantFiled: January 6, 2016Date of Patent: October 29, 2019Assignee: Cook Medical Technologies LLCInventors: Joanna Lynn Rosenbaum, Andrea Christine Lawrence Mydosh

Patent number: 10456566Abstract: A balloon can be rather easily pressed against an inner wall inside a lumen using a proper pressing force. A balloon has a dilating/deflating section that forms a hollow internal space, and that deflates by the internal space being decompressed, and a support section that is arranged in the internal space so as to deflate in response to the deflation of the dilating/deflating section, and that supports the dilating/deflating section so as to dilate outward in a state where the internal space is under atmospheric pressure.Type: GrantFiled: January 21, 2016Date of Patent: October 29, 2019Assignee: TERUMO KABUSHIKI KAISHAInventors: Kosuke Nishio, Riyaheh S.
